Torque compensation method and system, hybrid electric vehicle and machine-readable storage medium

Abstract

Embodiments of the present invention provide a torque compensation method and system, a hybrid electric vehicle, and a machine-readable storage medium. The torque compensation method includes: during the running of the hybrid electric vehicle, judging whether there is a shift demand to generate a first judgment result ; when the first judgment result is yes, further judge whether the shift demand is the shift demand of the motor to generate the second judgment result; if the second judgment result is yes, further judge whether the engine is in double The clutch gearbox has an odd gear and participates in driving to generate a third judgment result; if the third judgment result is yes, the engine is controlled in a motor gear shifting torque compensation mode to perform torque compensation on the motor. The method uses the engine to perform torque compensation on the motor to make up for the insufficient torque generated by the action of the gear shift synchronizer of the motor, so that the power performance of the hybrid electric vehicle is guaranteed.

Description

technical field [0001] The present invention relates to the field of vehicles, in particular to a torque compensation method and system, a hybrid vehicle and a machine-readable storage medium. Background technique [0002] With the increasingly stringent national fuel consumption regulations and the implementation of the "double points" policy, new energy vehicles have become a trend, and hybrid vehicles are popular with the public due to their good power performance. [0003] At present, hybrid models are mainly distinguished by power systems. Japanese car companies represented by Toyota use power split hybrid systems, which are compact in structure and good in power economy, but complex in control and high in technical barriers; German companies headed by Volkswagen use P2 Or parallel hybrid systems such as P3, with little change to the traditional powertrain. At present, the P2.5 parallel configuration is more popular in China. In this configuration, the motor is integra...
